WebWhen e = B/6, q min becomes zero, and the further increase of the eccentricity ( e > B/6), negative pressure will be generated on the soil. It is the development of tension in soil. In this situation, there will be a separation between the soil and the footing. During the design, we have the bearing capacity of the soil. In geotechnical engineering, bearing capacity is the capacity of soil to support the loads applied to the ground. The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. Ultimate bearing capacity is the theoretical maximum pressure which can be supported without failure; allowable bearing capacity is the ultimate bearing capacity divided by a factor of safety.
